for Alton Court. The three days of traffic counts were averaged and trip rates were calculated to apply to the Alton Court project. The calculated trip generation rates based on the Charleston counts and the resulting trip generation for Alton Court is summarized on Table 2. Table 2 indicates that the Alton Court development is estimated to generate 85 trips during the morning peak hour, with 32 inbound and 53 outbound trips, and 40 trips during the evening peak hour, with 29 inbound and 11 outbound trips. Trip Generation Comparison The proj ect site currently contains a resource center/warehouse for the Santa Ana Unified School District. A trip generation comparison was conducted to document the existing trips entering and leaving the site. The data are summarized on Table 2, previously referenced. The traffic counts summarized on Table 2 indicate that the school district resource center/warehouse is currently generating 86 trips during the morning peak hour, with 55 inbound and 31 outbound trips, and 83 trips during the evening peak hour, with 39 inbound and 44 outbound trips. This comparison shows that the school district resource center/warehouse is currently generating the same level of morning peak hour traffic that would be generated by the proposed residential project and is currently generating about twice the evening peak hour traffic that would be generated by the proposed residential project. TRIP DISTRIBUTION Project trip distribution assumptions for the project site were developed based on the observed trip distribution patterns of the adjacent Charleston residential development. Based on these trip distribution patterns, the new trips to be added to the street system by the proposed proj ect were calculated, and are shown on Figure 2. EXISTING PLUS PROJECT CONDITIONS An Existing plus Project analysis was conducted to evaluate traffic conditions with the project. Existing plus Proj ect traffic volumes are shown on Figure 3. Each intersection was re-analyzed using the ICU and HCM methodologies with these traffic volumes, and the results are shown on Table 1, previously referenced Based on the ICU analysis, the three study intersections would continue to operate at LOS B or better during both peak hours with the proposed residential project. Based on the HCS analysis, the intersection of Alton/Fairview is proj ected to continue to operate at LOS D or better during both peak hours based on intersection delay with the addition of proj ect traffic. The intersection of Alton/Greenville is projected to continue to operate at LOS E during the morning peak hour and at LOS D Traffic Analysis for - 7 - October, 2007 Alton Court Residential Development 75A-138
